Frequently used terms http://home.eunet.no/~presno/bok/v4.html
Packet switching
Sending data in packets through a network to some remote location. The data to be sent
is subdivided into individual packets of data, each having a unique identification and
carrying its destination address. This allows each packet to go by a different route. The
packet ID lets the data be reassembled in proper sequence.
Password
A code used to gain access to a locked system. Good passwords contain letters and
non letters and are not simple combinations such as "virtue7". A good password might
be: Ho/t$1 6.

connected. (See COM Port above.)
On the Internet, "port" often refers to a number that is part of a URL, appearing
after a colon (:) right after the domain name. Every service on an Internet server
"listens" on a particular port number on that server. Most services have standard port
numbers. For example, Web servers normally listen on port 80. Services can also listen
on non standard ports, in which case the port number must be specified in a URL when
accessing the server, so you might see a URL of the form:
gopher://peg.cwis.uci.edu:7000/
This shows a gopher server running on a non standard port (the standard gopher port is
70).
Finally, "port" also refers to translating a piece of software to bring it from one type
of computer system to another, for example to translate a Windows program to make it
run on a Macintosh.
Prompt
Several times during interactive dialogs with online services, the flow of data stops while
the host computer waits for commands from the user. At this point, the service often
presents the user with a reminder, a cue, a prompt. These are some typical prompts:
?
